the industrial revolution in the 18th century when you start harnessing all other kinds of energy. during that long block of time from a couple of million years ago until the industrial revolution, there was a point about 10,000 years ago when human beings began to farm, began to practice agriculture, and that harnessed a lot more energy than was possible by just hunting and gathering wild resources. keach: in the old world, we know that agriculture sparked the development of the world's first cities in places like sumer in ancient mesopotamia. but how did farming begin in the new world ? when scotty macneish first came to the tehuacan valley in 1962, he was seeking the answer to one simple question -- did agriculture evolve here or was it introduced from the old world ? then we'll measure out from the corners. keach: in a stratum of the purron cave that had been laid down thousands of years later than those in which he found the hunters and gatherers, macneish made a discovery that exceeded all expectations. macneish: this is a corn cob, and it's a real little one. keach: it may

protein energy malnutrition that we see, can be as high as 30 to 50%. usually the children die from routine infections like diarrhea or pneumonia. in fact, pneumonia is the most common cause of death. children who are severely malnourished appear anorexic. they do not want to eat. they're often very depressed. their heads are low. they stop talking. they stop walking, and they're severely dehydrated and suffering from infectious diseases. perhaps the most extreme case of malnutrition the team witnessed was annis-- a tiny wisp of a girl, two and a half years old. annis is just skin and bones and a head. and i looked at her, and i looked at the weight, and i asked the mother how old she is and the mother told me. and i said, "it's not possible." so i took annis myself back to weigh. i saw the scale, it said 4.2 kilos, took annis off, measured her height, put her back on the scale. i still couldn't believe it. it was amazing to me that annis was still alive. the highest mortality for children so severely malnourished occurs in the first few days. if you overfeed these kids they will di

[laughter] hey, but the point, back again, you're up at the top of the hill and it's cool up there. and you know what you can tell your friends? hey, gang, you know why it's so cool up here? because warm air rises. let me ask you a question, does warm air rise? you guys know about that from b

without eating, which undermines not only my health but my energy. this i intend to restore and i am off to panama to live like a savage. narrator: still looking for paradise, gauguin arrived in panama in 1887 with charles laval, a younger artist. work had begun on the canal which would open the floodgates to another wave of colonial adventure. gauguin found work with a construction firm. after two weeks and bouts of malaria and dysentery, the painters made off for martinique and found a new storehouse of ideas. reader (gauguin): we have found a native hut oa plantation. below us, the sea and a sandy beach for bathing and on either side coconut palms and other fruit trees for a landscape painter to feast on... what appeals to me most is the people, and every day brings a ceaseless coming and going of island women in colorful fad finery with their infinite variety of graceful movements. narrator: gauguin returned to paris late in 1887 and sold some of his martinique paintings. the perceptive critic octave mirbeau was spellbound. ra sacred, eden-like abundance in these forest interiorstery
